PCB

The utility model discloses a PCB, its technical scheme main points include the PCB body, the PCB body includes semi -solid preparation layer, base plate and lower semi -solid preparation layer, all be provided with the fixed orifices that is used for fixed this PCB body on four corners of PCB body, PCB body edge width direction's both ends are provided with erect the same with the PCB body of thickness respectively and are connected soft, erect left part, middle part and the right part of connecting soft fixed connection PCB body. The utility model discloses utilize after the fixed orifices fixes this PCB body at this PCB, if suffer the external force extrusion and then make the PCB body take place deformation, connect soft elastic deformation ability and then avoid covering the PCB bodyat the position of fixed orifices breaking occur through erecting, thereby avoid PCB to influence the use to PCB because of fixing, simultaneously because soft of cross linkage falls into the left part with this PCB, middle p
